Abstract: Catalytic efficiencies of PA100,Amberlyst21,D301R and D66 on the disproportionation reaction of trichlorosilane are investigated in a fixed-bed reactor and PA100 is found to be the optimum catalyst.The kinetics for the disproportionation reaction of trichlorosilane is studied by using PA100 as catalyst at reaction temperature between 330 K and 400 K.Effects of the reaction temperature,loading amount of catalyst and particle size of the catalyst on the disproportionation reaction of trichlorosilane are investigated.The test results indicate that within a certain temperature range,the higher the reaction temperature,the faster the reaction rate and the higher the trichlorosilane conversion rate at equilibrium.Moreover,neither catalyst dosage nor particle size affect the conversion rate of trichlorosilane at equilibrium.According to the disproportionation mechanism of trichlorosilane and experiments,a kinetic model for the disproportionation of trichlorosilane is established and chemical equilibrium constant is calculated.Based on the Arrhenius equation,the activation energies for the forward and reverse reactions of trichlorosilane disproportionation are 129.60 kJ·mol-1 and 61.74 kJ·mol-1,respectively.PA100 is characterized by SEM and TEM.
